14 DAY TRIAL // Adobe just released the stable build for Lightroom 4.2. Besides adding support for a slew of new cameras, the new revision also addresses a variety of bugs.
Among the problems fixed is the one with stacked images being hidden in Grid and Filmstrip views, which happened when the images got unstacked as a result of enabling auto-stacking.
Also repaired is a minor glitch that occurred when fast scrolling through the Filmstrip view, and consisted in displaying a gray thumbnail for a short moment, instead of the actual image preview.
Additional repairs touch on failure to publish images to Facebook on occasions, sharpening effect not being applied on books exported in JPEG format or unresponsive Luminance Noise slider when Clarity was greater than zero.
A bug with audio not playing in video files after creating a slideshow containing music, specific to Windows 7, was also eliminated. You can check the full changelog here.
